After another few days, Zhang Wuji's wound was completely healed. He then used his Art of Nine Yang help Yang Xiao, Wei Yixiao and the Five Wanderers force out the Xuan Yin Finger's cold poision. Within three days, they had completely recovered from their internal injuries and wanted to leave the secret tunnel and destroy the enemy. Zhang Wuji said: "You've just recovered from your injuries and your inner strenght has not returned completely. Since you've already been patient for so long, waiting a few more days can't hurt." For the next few days, everyone worked hard preparing themselves. Those with mediocre kungfu sharpened sabres and swords and those with better kungfu practiced regulating their chi. The Ming Cult had suffered one humiliation afte another since the six major sects beseiged Brightness Peak. Now their frustration was boiling over, needing an outlet to be released.
One night, Yang Xiao explained the Ming Cult's creed, aim, and rules, their main power centres in different places, and the abilities and characters of their leaders to Zhang Wuji. They heard the sound of iron chains clanging as Xiao Zhao approached to serve them tea. Zhang Wuji said: "Left Emissary Yang, this young lady has committed no offence. Please unlock the chains and release her!"Yang Xiao said: "I won't dare disobey sect leader's orders." He immediately called for Yang Buhui and told her: "Buhui, the sect leader wants you to unlock Xiao Zhao's chains." Yang Buhui said: "I left the key a drawer in my room." Zhang Wuji said: "That's not a problem. The key wouldn't have been burnt."
Yang Xiao waited until his daughter and Xiao Zhao had left before saying: "Sect leader, though Xiao Zhao is very young her behaviour is quite strange. We have to be cautious towards her." Zhang Wuji asked: "What are her origins?" Yang Xiao answered: "Half a year ago, I took Buhui on a trip down the mountain. We found her in the desert, crying over two dead bodies. We asked her what happened and she replied that they dead were her parents. Her parents had offended a government officer in the Central Plains and her family had been exiled to the Western Regions to work for the military. A few days before, unable to bear their treatment by the Mongol soldiers any longer, they had tried to escape. However, her parents sucummed to their injuries and exhaustion. I saw that she was a young girl all alone in the world. Though her face was ugly, from her speech she was not stupid. So I helped her bury her parents, then took her in as Buhui's maid." Zhang Wuji nooded his head thinking: "So both Xiao Zhao's parents have passed away. Her life is really tragic, no different from me." Yang Xiao continued: "Back in Brightness Peak, one day when I was teaching Buhui martial arts, Xiao Zhao was listening nearby. I was explaining the sixty-four Bagua positions. Buhui had not get grasped the idea when I saw Xiao Zhao's eyse look at the right position." Zhag Wuji said: "It's probably because she's very intelligent. That's why she understood the concept before Sister Buhui." Yang Xiao said: "That's what I thought at first, I was very happy. But when I considered it further, I became suspicious. I delibreately recited an extremely difficult formula, something I had never taught Buhui. Then I recited some Bagua positions worngly, only to see her frown slightly – she had noticed the mistakes. Since then I've kept this in mind, knowing that this little girl has been taught by a great master and probably has powerful kungfu. She must have been sent to Brightness Peak by someone to spy on us."
Zhang Wuji said: "It might be that her father was an expert of the Book of Changes and she learnt it from him." Yang Xiao said: "Sect leader please reflect: the literary knowledge of the Book of Changes is different from its application to martial arts. If Xiao Zhao had learnt it from her parents, then they must be top wulin experts. How could they have been killed by Mongol soldiers? At that time, I pretended I had not noticed anything. A few days later, I casually asked her about her parents' names and origins. She smoothly asnwered everything without revealing the slightest information. At that time I showed no reaction, all I did was warn Buhui to be careful with her. Then one day, I told a joke and Buhui laughed loudly. Xiao Zhao was nearby and she couldn't help laughing as well. She was standing behind Buhui and I, we could not see her. But it so happened that Buhui was playing with a dagger in her hand and her reflection was caught clearly in the dagger. She was no ugly girl! Her features were much more beautiful that Buhui's. But when I turned around, her face had reassumed its squinted eye and twisted mouth look." Zhang Wuji smiled saying: "To twist her face to look ugly all the time…that must be quite difficult." In his heart he thought: "Left Emmissary Yang is truly amazing. There's no Xiao Zhao could continuely fool someone like him." Yang Xiao continued: "Even then I kept silent. Late that night, I quietly went to my daughter room to watch Xiao Zhao. I saw that girl lave Buhui's room. She went to the eastern side of the house looking for who-knows-what. She searched carefully in every room and corner. Unable to bear it any longer, I revealed myself and questioned her – what was she looking for and who order her to spy on Brightness Peak. She calmly replied without panic that no one had sent her. She just enjoyed playing around and being inquisitive. I tried everything to threaten and persuade her but she told me nothing. I locked her up and starved her for seven days and seven nights. Even when she was faining from starvation she wouldn't say anything. Finally, I locked her up in those iron chains. When she moves, the clanging sound follows so she can't sleathily harm Buhui. I didn't kill her because I wanted to find out her origins. Sect Leader, this girl is definately a spy sent by some enemy. Based on her proficiency in Bagua positions, she's either from Kunlun or E'Mei Sect. But she's still a young girl, no great danger to us. Let her serve you. It is her good fortune that you're willing to show mercy on her."
Zhang Wuji stood up and laughingly said: "We've been cooped up in this underground prison for so long. Don't you think it's now time to go up and stretch our legs?" Yang Xiao asked happily: "Are we going out now?" Zhang Wuji answered: "Those who have yet to recover cannot fight. They don't have to contribute to our cause now. The rest can all go out. What do you think?" When Yang Xiao gave the order, the secret tunnel was filled joyous cheering and bustling activity.
They had entered the tunnel through the entrance in Yan Buhui's room. Now they went out through the side entrance, coming out behind the mountain. Zhang Wuji pushed away the stone blocking the entrance, let everyone through, then pushed the stone back into place. The Earth Flag Leader Yan Yuan was the Ming Cult's strongest man. He experimentally tried to move the rock but it would not even budge. It was as if he was a dragonfly trying to move a stone pillar. His admiration for his young sect leader increased.
They did not want to alert the enemy so the came out of the secret tunnel silently. Not even a cough was heard. Zhang Wuji stood on top of a large rock. The moonlight shone down on them. To the west were the ranks of the Heavenly Eagle Sect: the three halls – Heaven's Secret, Purple Secret and Heaven's City – and the five branches – Divine Snake, Green Dragon, White Tiger, Crimson Sparrow and Black Valiant. They formed orderly rows, each with its own leader. On the east were the Ming Cult's Five Flags: Gold, Wood, Water, Fire and Earth. The Flags were arranged in the Five Elements position with their leaders and deputy leaders at the head. In the middle were the Brightness Peak troops, the Four Gates under Yang Xiao's command – Heaven, Earth, Wind and Thunder – headed by their own leaders. The Heaven Gate was made out of Central Plains men, the Earth Gate out of Central Plains women,the Wind Gate out of members who had taken religious orders, and the Thunder Gate out of non-Chinese from the Western Regions. Though most of the Five Flags and Four Gates members had been wounded in last battle, they were all full of spirit and vigour. The Green Wing Bat King Wei Yixiao, Leng Qian and the rest of the Five Wanderers stood protectively behind Zhang Wuji. Everyone waited respectfully for the Sect Leader's orders. Zhang Wuji slowly said: "Enemies have invaded our territory. No matter how patient we are, we cannot tolerate this. However I don't want any needless killing and injuring. Keep this in mind. The Heavenly Eagle Sect will attack from the west under the command of Sect Leader Yin. The Five Elements Flags will attack from the east under the command of Wood Flag's Flag Leader Wen Cangsong. Left Emmisarry Yang will lead the Heaven and Earth Gates to attack the north. The Five Wanderers will lead the Wind and Thunder Gates to attack the south. Bat King Wei and I will direct the proceedings." Everyone bowed and accepted their orders.
